The Road Network data is structured based on the Swedish County jurisdiction boarders.
Each County has four different data sets for download, three containg the same gravel data but in different file formats and one dataset for the paved roads.
The usage of the three different gravel files depends on what type of client you will use to render it with, I added all three just in case
1) All data is publicly available for Non Commerisal Use from Transportstyrelsen
2) Be civil, if you use it, don't claim it, give credit
